Ultra-low jitter, EEPROM programmable oscillator for medical imaging and test and measurement | SIA | 8 | -40 to 85

The LMK61E2 device is an ultra-low

jitter PLLatinum™ programmable oscillator with a fractional-N frequency

synthesizer with integrated VCO that generates commonly used reference clocks. The

outputs can be configured as LVPECL, LVDS, or HCSL.

The device features self start-up from

on-chip EEPROM that is factory programmed to generate 156.25MHz LVPECL output. The

device registers and EEPROM settings are fully programmable in-system through

I2C serial interface. Internal power conditioning provide excellent

power supply ripple rejection (PSRR), reducing the cost and complexity of the power

delivery network. The device operates from a single 3.3V ± 5% supply.

The device provides fine and coarse

frequency margining options through I2C serial interface to support

system design verification tests (DVT), such as standard compliance and system

timing margin testing.
